JOINT.

Application mea september 1, 1925. serial No. 153,927.

The joint is intended to insulate" different parts of structures subjected to jar, such as the body and chassis ofan automobile and as exemplified is secured between the body and s chassis of an automobile. Features and details of the invention will appear from the specification and claims.

The invention'is illustrated in the accompanying drawings as follows tion through the joint.

Fig. 2 a plan view of the joint.

Fig. 3 a section on the line 3-3 in Fig. 1.

1 marks the channel of the automobile la frame, and 2 the sill of the body. These may be of any desired construction. A plate 3 has perforations 4 near its ends and bolts 5v extend through the perforations 4 and perforations 6 1n the channel and are secured 2o by nuts 5 on to the channel. An upper plate 7 is shorter than the lower plate so as to give clearance for the bolts and permit these bolts to be readily put in place. The plate has a central perforation 8 and` a nut 9 is arranged between the plates, the nut having a projection extending into the perforation 8. The perforation is out of round, or has a straight portion 10 which'is engaged by a similar surface or straight portion 11 on the 3U nut so as tolock the nut against turning. Or the nut is placed in the perforation dinarily with a pressed fit but this is not essential as when the parts are in place the nut is locked in place by the channel. The plate 3 has an opening 12 opposite the opening 8 and somewhat larger than the opening 8 so as to per mit the insertion of the nut.

A. rubber insert 13 is arranged between the plates 3 and 7 and bonded to the opposing ,40 surfaces of the plates so as to' tie them together. This bonding is accomplished in any of the Well known ways but preferably as the rubber is vulcanized. A bolt 14 extends through the sill 2 and is screwed through the nut 9. An opening channel in line with theo `ening in the nut, the opening 15 being somew at larger than the bolt so as to permit some movement of the rubber without metal engagement ofthe bolt 5 Withthe channel. The opening 15 may simply 'provide means for added over length, the end of the bolt extending through the nut but preferably the bolt extends through the Fig. 1 shows a central longitudinal sec-l 15 is arranged in thel plates and securing opening 15 a suilicientdistance to receive a nut 16. on the underside of the channel, the nut being, however, out ofoontact with the channel. v

The nut preferably extends into the plate 3 so as to give the nut sufcient thread length and in many cases it is desirable to make the thickness of the rubber-and plates some` what smaller than that shown and here the added length of nut is of importance. yThe nut, however,is out of engagement with the walls of the openin 12 andein the construction shown the rub er can be vulcanized in place leaving the openings 8 and the opening in the rubber corresponding thereto and the nut placed in position after the vulcanizing operation. l l

With this construction it will be seen the sill is entirely insulated from the frame and the rubber permits a slight yielding to pre` vent distortionof parts. By extending the bolt through the sill and channel these parts are positively loclied together should there be any failure of the rubber.

It will be noted that the nut and extension of the bolt limit the side slip of the plates relatively to each other andrthis may be made as great, or as small as desired.

What I claim as new is 1. In a joint, the combination of two opposing joint plates; a rubber insert between the plates bonded to the opposin plates; and securing means on each of the pilates, the securing means on one plate being' olf-set as to the securing means on the other plate, the. securino means on one plate extending between the plates and the rubber.

2. In a joint, the combination of two overlapping joint lates; a rubber insert between the plates bon ed to the opposingv lates; and a securing means secured to one o the plates and extending into lapping and non-contacting vrelation to the other plate" and between the rubber. i

3. In a joint, the combination of `two opposing joint plates having oppositely placed openings,- the opening in one plate being larger than the other; a rubber insert between the plates bonded to `the. opposineI means inserted through the larger opening and into engagement'with the walls of the smaller opening. 'j Y 4. In a joint, the combination of two opposing joint plates having oppositely placed openings, the opening in one plate being larger than the other; a rubber insert between the plates bonded to the opposing plates; 5 and a'nut inserted through the larger opening 'into engagement with the walls of the smaller opening.

5. In a joint, the combination of two opl posing joint plates having oppositely placed openings, theA opening in one plate being larger than the other; a rubber insert between the plates .bonded to the opposing plates; and a mit inserted through the larger opening into engagement with the walls of the smaller opening, said nut extending into but out of eontactwith the walls of the larger opening.

6. In a joint, the combination of opposing joint plates; a rubber insert between the plates Abonde'd to the opposing plates; and a nut arranged between the plates.

7. In a joint, the combination of posing plates, one the other of said plates, the ends of said longer plateforming a securing means for such plate; a securing means on the other of said plates; and a rubber insert between said plates bonded to the surfaces of said plates.

8. In a joint, the combination of two opposing plates, one plate extending beyond the other of said plates, the ends of said longer plate forming a securi means for such plate; a securing means o the other of said plates, said means ,being arranged between the plates; and a lrubberinsert between 'said two opplates bonded to the surfaces of said plates.

9. In a joint, the combination of two opposing plates, one plate 40 the other of said plates, the ends of said longer plate forming a securing means for I such plate; a securing means on the other of said plates, said means being arranged between the vplates in lapping non-contacting relation to the longer plate; and a rubber insert between said plates bonded to the surfaces of said plates.

10.y In a j omt, the combination of two overlapping joint lates; azrubber insert between the plates bon ed to theopposing plates; and means between the lates limiting the side movement of the plates relatively to each other. is A 11. In a joint, the combination of two overlapping jolntplates; a rubber insert between ithe platesv bonded to the opposing plates; and securing means for one of said platesarranged between the plates, said means limiting the relative sidemovement of said plates.
